I've been thinking about getting a trailer for a while, and I noticed Edinburgh Cycles have an Orbit trailer for just over £100. It's payload is 50kg, so almost a third more than a BOB, and comes with a removable carry box. By the time I've takn into acount getting a Yak sack to go with the BOB, the Orbit works out at less than half the price. I know being a 2 wheeled model, It's not going to be suitable for off-road use, but as it would mainly be used for groceries, trips to the recycling centre, garden centre etc. that wouldn't be a problem.
My only major concern is the seatpost hitch, rather than a stay or skewer monut.
Any experience? Any comments? Any suggestions?
